The BI would be more trouble than it's worth, to be honest.
On the otherhand, the VVS did have lend-lease P-47Ds. Those may have been useful.
I put myself in the shoes of the Soviet military leadership and think: what can we do against the Allied bombing offensive?
I know how bad it can hit - there is plenty of evidence on the ground in our occupation zone.
I have no illusions about the capability of the domestic industry and engineering, - whatever nice airframes are offered by the designers, the problems with the engines are not resolved. High octane fuel will be in deficit.
And the days of a propeller aircraft are counted. What are the options?
Operation Osoaviakhim can be conducted immediately after the Unthinkable begins and Cambridge Five and other spies can be given orders to boost their efforts. Yet I don't know how valuable German engineers will be and spy rings will not send me complete aircraft or engines.
I can put my hopes into
RD-1 or another (German?) engine attached to new fighters (
La-7R-2, Yak-3R,
Su-7 etc). But I understand that this is a temporary solution.
Now, what about this BI rocket fighter... It didn't impress anyone and was closed recently. However, it was a small-scale program with poor funding, outside of the main attention of the Ministry of Aviation Industry. Why not resume the program and provide it with all the resources needed?
By the way, if I am
Shakurin or
Novikov, I know that not just my career but my life is at stake here.
